+## Part 2 - Play Pong
+
+Implement an agent to play Pong - the OpenAI Gym
+[integrates an Atari environment](https://github.com/openai/gym#atari), and you
+can start by trying
+[example agents](https://github.com/openai/gym/tree/master/examples/agents). The
+random agent is a simple initial example, and the keyboard agent can allow you
+to actually play the game yourself (and potentially use that data to train
+some other agent). The example notebook from the first coding challenge has
+useful snippets of code for visualizing what is going on.
+
+After getting set up and playing with a few agents, check out
+[this article](http://karpathy.github.io/2016/05/31/rl/) on using policy
+gradients to train a model to play Pong. Code your own agent based on this
+technique - [this video](https://youtu.be/YOW8m2YGtRg) illustrates the end
+result of such an agent.
+
+
+## Part 3 - An environment of your choice
+
+OpenAI supports
+[many interesting environments](https://github.com/openai/gym#environments) -
+pick one, and start by trying to run existing agents and find prior work (as
+with Pong). Then take a shot at writing your own - this is open-ended, so have
+fun and explore something that interests you, but also chat and share what
+you're doing so people can collaborate and learn from one another.
